Enbrel works by decreasing a certain protein produced by the immune system. The immune system helps the body fight infections. In people with autoimmune disorders, the immune system mistakes the body's own cells for invaders and attacks them.

Enbrel is used to treat the symptoms of rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis, and to prevent joint damage caused by these conditions. Enbrel is also used to treat plaque psoriasis in adults and polyarticular juvenile idiopathic arthritis in children who are at least 2 years old.

Enbrel is not a cure for any autoimmune disorder and will only treat the symptoms of your condition.
